Improvement in plows



NITED STATES PATENT OFFICE.

DANIEL RHODES, OF PAWTUXET, `RHODE ISLAND.

IMPROVEMENT IN PLOWS.

Specification forming part of Letters Patent No. 42,40 l dated April I9, 1864.

To all whom it may concern:

Be it known that I, DANIEL RHoDEs, of PawtuXet, in the county of Kent and State of Rhode Island, have invented a new and useful Improvement in Plows; and I do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawing, making a part of this specification, said drawing being a perspective view of my invention.

The object of this invention is to obtain a simple and efficient device, which may be operated at any time when the plow is in use, for varying the line of draft, so as to give the point of the share a greater or less tendency to eilter the ground, and thereby regulate the depth of the furrow, as may be desired, and keep the same at a desired uniform depth, however undulating the surface of the ground may be.

To enable those skilled in the art to fully understand and construct my invention, I will proceed to describe it.

A represents the beam of the plow, B the handles, C the mold-board, and D the share. These parts may all be constructed and arranged in the usual way, and therefore do not require a minute description.

To the front end of the beam A there is attached a metal plate, E. This plateis curved or bent, so as to form a loop or guide of cuived or segment form.

F is a lever, which is attached to the upper surface ofthe beamA, a being its fulcrum-pin. The back part of the lever F passes through or is tted in a vertical guide, G, which is attached to the back part of the beam, and has a rack, b, secured to it, with which a catch or yielding rod, c, engages. The front end oi' the lever F is connected by a joint or pin, d, with a small frame, H, the lower cross -piece of which is fitted in the loop or guide E, and is 'provided with a roller, l, to reduce the friction in moving the frame up and down. The

lower ends or parts of the side pieces, e e, of the frame H project forward at right angles with the main parts, and the front ends of said 'by this simple arrangement the line of draft may be raised-that is to say, raised or lowered to suit'the undulation of the ground, and the depth of the furrow rendered uniform throughout.

Plows have been constructed with adjustable clevises; but the great diflculty attending their operation has been their liability to get out of repair, owing to a lack of a rm connection between the clevis and the plow. This difliculty is fully obviated by my invention.

I am aware that it is common to raise and lower the front of a plow-beam by means of a lever to regulate the depth of plowing; and also that in some instances the clevisitself has been raised and lowered upon the beam by similar means. My peculiar manner of attaching and moving the clevis on the beam imparts great strength, secures it against a longitudinal or lateral strain, at whatever height it may be placed, renders it more compact and readily applicable to common plows, and also adapts it to be moved with greater ease wlhile the plow is in motion.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

The arrangement of the vertically-moving frame H, armsf, roller R, and loop E with the clevis I, beam A, lever F, and guide G, all in the manner herein shown and described.

DANIEL RHODES.
